BLUINQ- SPECIFICATION forming part of Letters Patent No. 384,804, dated June 19, 1888.

Applhmtinn filed April l9, lSB'I.

To all whom it may concern.-

-3e it known that l, Gnonon HENRY Wmss, a subject of the Emperor of Germany, and now residing in Newton, in the county of Middlcscx and State of Massachusetts, have invented a new and useful Improvement in the Preparation of Bluing for Marketing and Use, of which the following is a full, clear, and exact description, reference being bad to the this specification, in explaining its nature.

l;hc invention relates to the method of marketing and using bluing which comprises the ap 'illcation of a bluing solution to strips or sheets of paper of any desired size, which sheets act to hold the bluing for transportation, and also as a vehicle by which the bluing is introduced into the water or washing solution. Heretolore these sheets have been prepared for use by coating both surfaces of the sheet with bluing composition and by saturatmg the. sheet with a bluing composition,so that the entire sheet is covered upon both sides, or filled with the bluing composition, and these sheets have been loosely packed in envelopes [or transportation and marketing. \Vhen the bluing sheets or strips are thus prepared, it is necessary in using them to submerge the entire sheet or strip in water or other liquid to which the bluing is applied, and as this is done by hand it follows that this cannot be done without wetting and bluing the fingers to a greater or less extent; and as the sheets are packed together in an envelope it is praetlcally impossible after one sheet has been taken from the envelope to take another sheet therefrom without wetting some of the sheets in the envelope, which may spoil them to some extent. My invention is designed to obviate the ob- Jectons which arise from this manneriofspreparing the bluing for use; and it comprises, first, a blued sheet or strip which consists of a sheet or strip "of paper saturated or coated with a bluing solution upon a portion of one or both surihces, leaving a portion of the sheet uncoated or unsaturated with the bluing composition, which acts as a tab whereby the sheet'may be held by the thumb and fingers while the portion of the strip or sheetwhich suitable thickener.

carries the bluing 'is introduced into the water or other liquid.

The invention further relates to the assembling of these sheets or pages thus prepared in the-form of a book,with the uncovered sec tions or tabs at the outer ends of the blued sheets or strips which make the leaves of the book, the inner ends of the sheets or strips being secured to each other in any desired way, and preferably within covers of paper or any other suitable material. The sheets, preferably, are also perforated or weakened close to the seam uniting them together, so that they may be readily detached or removed from the book.

Referring to the drawings, Figure 1 represents the leaves or sheets incorporated in a book, the book being represented as open. Fig. 2 is a section through the book when closed.

A represents the sheets or strips carrying the bluing. a represents the portions of the sheets, strips, or leaves covered or saturated with the bluing composition; and a, the tab ends thereof, which are free from bluing. preparing these sheets or slips for use I take paper of any suitable quality, preferably Manila paper, and cut it to the form of the sheet or strip desirei I then prepare acomposition of blning, which may be made in any desirable way, but which I prefer to make substantially as follows: One solution which is desirable for this purpose I make by taking soluble Prussian blue or a suitable anilineblue and dissolve the same in water, obtain a solution as concentrated as possible. In case aniline-blue is used there should be added some acetic acid to the water in order to develop the color thoroughly. There maybe added to the solution dextrine,

I would say, however, that there are other ways of making a solution suitable for application to paper in the manner specified, and that I do not confine myself in' practici herein specified. Into this solution the sheets or strips are dipped by their tab ends, and so that about from two-thirds to three-quarters of each strip or sheet shall be immersed in the solution, and they are allowed to remain so as to 8 5 starch,or other 0 ng myinvention'to the one theretoo tion, by which the ,sheet or leaf can be handled in sulliciently long to properly receive the blning. if the paper is of a porous character, its substance is more or less saturated with the solution. Ifitis not porous,thcn the luing covers the surfaces thereof submerged ings as secured together by thread butI would say that I do not confine myself to this means of attaching them, as they may be secured together in any desirable way. I prefer, as a rule, to inclosc them within a cover, B, of a size sufficient to cover and protect the blued sheets, and when a cover is used the sheets are assembled within it, and are united to each other and to the cover by thread or other fastening passed through the cover and close to its back, the cover generally being formed from a strip of unblued paper of somewhat more than twice the length of the blued sheets.

\Vhere thick or tough paper is employed for the blued sheets or leaves,l prefer to perforate or otherwise weaken it close to the line of the fastening securing them togetheain order that the leaves or sheets may be easilydetached from the book.

I would say that the book or adapted to carry blning either by saturation or by coating, or both, and which shall also have either integral therewith or affixed thereto an unblued tab or seewithout soiling or dirtying the fingers. I would say, also,- that I do not confine myself to the use of paper as a vehiclefor carrying the bl uing, but may use in lieu thereof 2 other suitable material.

It will be observed that by this form of bh: sheet or leaf and method of securing them gether not only can the sheets be used wii out soiling the hands or anything else, but tl they may be used more economically, as t leaves are held together as a book time ofuse,and only as many are then remov rom the 00k as may be needed for proper preparing the water or liquid.

Having thus fully described my invention claim and desire to secure by Letters Patent the United States- Asan improved article of manufacture, leaf; sheet, or strip consisting of a lea terial having one section coated or saturate with a blning composition soluble, or substai tially soluble, in water, and having also a SC( tion free from blning, by which it may b handled without soiling the fingers, am adapted to supply the water or fluid with 1 given amount of blning, as and for the pur poses described.

2. As a new article of manufacture, a blue book containing a numberof strips or leaves of paper or other similar material having the inner sections, a, saturated or coated with a blning composition soluble in water and the outer sections, a, free from blning, as and for the purposes specified.

3 The due-book comprising a number of sheets, leaves, or strips of paper or other material, sections of which are coated or saturated with a blning composition, and sections of which are uncoated or unsaturated, and which are used for tabs, united together and to their holdingcovers, as and forth'e purposes described.

4. The blue-book comprising the covers B, the blued sheets or leaves A, having the blued sections a and the tab ends a united to each other and to the cover, and having perforai tions or weakened close to the line of the attaching-seam, as and for the purposes described.
